With the continuous development of wearable electronic devices, the demand for energy storage devices with characteristics such as "light", "thin", and "flexible" is becoming increasingly urgent in the market. Flexible supercapacitors have the characteristics of fast charging and discharging rate, high power density, long cycle life, and safety and environmental protection. They are a promising energy storage device and have attracted much attention. In this book, by studying the preparation and characterization of graphene based flexible electrode materials, we aim to develop...

Recently, graphene-based electrode materials and flexible supercapacitors have received extensive research and rapid development. However, the application of electrode materials in wearable electronic devices is often limited due to high preparation costs, complex processes, difficulty in assembling flexible devices, and poor stability. Therefore, the low-cost, efficient and rapid preparation technology for high-performance graphene-based flexible electrode materials, as well as the development of high stability flexible device, are of great significance for improving their practical value....
